50%氟吗啉+乙膦铝防治葡萄霜霉病田间示范试验

Field Demonstration Experiment of Grape Downy Mildew Control with a 50% Flumorph Plus Fosetyl-Aluminium Package Mix

田间示范试验结果表明:50%氟吗啉+乙膦铝可湿性粉剂防治葡萄霜霉病效果较好,50%氟吗啉+乙膦铝可湿性粉剂1000mg/L、667mg/L两个浓度处理的防效分别为93.0%、90.2%。69%烯酰吗啉+代森锰锌颗粒剂1380mg/L防效为84.5%。72%霜脲氰+代森锰锌可湿性粉剂1440mg/L防效为82.8%。

In a demonstration field trial, a prepackage mixture of flumorph plus fosetyl-aluminium 50% WP provided relatively good control of grape downy mildew, with application concentrations of 1000 and 667 mg/L providing 93.0 and 90.2% control, respectively. A 69% GR of dimethomorph plus mancozeb at 1380 mg/L gave 82.8% control while a 72% WP of cymoxanil plus mancozeb at1440 mg/L provided 84.5% control.
